Hello again,

for the first question assuming the following situation:

file: header_a.hpp

#if defined VERSION_A
#include "version_a.hpp"
#elif defined VERSION_B
#include "version_b.hpp"
#else
#error "No version defined!"
#endif

file: source_a.cpp

#include "header_a.hpp"

Problem: kdevelop doesn't parse any of the files "version_a.hpp" and "version_b.hpp", at least not with custom Makefiles (like i use). The reason is obviously that kdevelop (the parser) can't know which file to include.

Any suggestions how i could solve the problem without breaking the conditional #include concept?

Second question:

namespace foo
{
enum my_enum
{
TYPE_ONE,
TYPE_TWO
}
}

template< my_enum name >
void do_something();

You would call it like
do_something< foo::TYPE_ONE >();

Code completion from kdevelop seems to have a problem with that template parameter as it doesn't suggest any completion but shows something like

"do_something< class type >() ..."

Any ideas for that too?

Both things tested on the latest stable 4.3.1 on Debian wheezy.

kdevelop is really great anyway

try this

#ifdef IN_IDE_PARSER
#define VERSION_A // or VERSION_B
#endif

at the top of the file depending on which codepath you want to test.
this creates a define that kdevelop sees but will not interfere with your code at compile or runtime
